Application filed J'une 30, 1896. Serial No. 597,633.. (No model.)

To @ZZ whom t may concern:

Be it known that I, JULES BEEUOHAUD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in the Construction of Supports for Walls, &c., of which the following is a specification.

This invention has for its object to provide new and improved means for underpinning the wall of a building and forming either a temporary or permanent support for such building, or a subbase or foundation, temporary or permanent, for any heavy structure, the construction being such that the wall or other structure can be raised or lowered as occasion may require. To accomplish this object, my invention involves the features of construction, the combination or arrangement of parts, and the principles of operation hereinafter describedand claimed, reference being made to the accompanying drawings, in which Figure l is a detail sectional View showing a portion of a building-wall and the manner of applying hydraulic jacks according to my invention to drive hollow columns at opposite sides of the wall for the purpose of supporting the wall temporarily or permanently. Fig. 2 is a similar View showing the manner of supporting the wall by the two sets of columns driven by opposite sides of the wall. Fig. 3 isa detail plan view. Fig. 4 is a detailvertical sectional view showing a portion of a wall supported by the two sets of columns in such manner as to permit alteration in or reconstruction of the lower portion of the wall. Fig. '5 is adetail view of the arrangement shown in Fig. 4. Fig. 6 is a detail vertical sectional view showing a modiication of my invention, and Fig. 7 is a detail sectional view showing the manner in which a subbase or foundation is provided beneath an old wall for the purpose of supporting a new wall or other structure built next the old one.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, whereinrlhe numeral l indicates the wall of a building or other `heavy structure which is to be underpinned or provided with a subbase or foundation, either temporary or permanent, according to my invention.

The wall indicated in the figures of the drawings is designed to represent the wallof any building already erected which is to bc underpinned or provided with a permanent subbase or foundation, or which is to be sup ported while it is altered or'rcconstructed in its lower portion. The wall may, however, be any high or tall or heavy structure other than the wall of a building.

In carrying my invention into effect I insert a beam 2 transversely into the lower portion of the wall l, so that the beam projects at its ends from the opposite sides of the wall in such manner that these projecting'ends constitute abutments for hydraulic jiacks 3 and 4, also located at opposite sides of the wall. The hydraulic jacks are designed to drive tubular sectional columns 5 and 6 into the ground for the purpose of placing at each side of the wall l a series of tubular columns, which may be utilized for permanently or temporarily supporting the wall, or partly as a subbase or foundation for a new wall or other structure erected beside the old wall or already-erected building or other object.

'Ihe tubular columns are preferably composed of iron, but they may be made of any metal suitable for the purpose, and are composed of a plurality of cylindrical sections adapted to be successively driven into the ground through the medium of the hydraulic jacks. In driving the columns the first sections are placed under and in alinement with the jacks, and the latter are operated to drive these sections perpendicularly into the earth. The next sections are attached to the upper ends of theiirst driven sections, and the second sections are operated by the jacks and also driven perpendicularly into the earth. These operations are proceeded with until the number of sections constituting the columns are driven to the depth necessary to reach bed-rock or other firm strata. During the driving of the sections composing the tubular columns the transverse beam 2 bears the superincumbent weight of the building wall and resists the pressure `of the jacks, whereby the latter may exert a very powerful force in driving or sinking the columns section by section in the manner described.

ICO

In order to prevent the wall from cracking, splitting, or otherwise rupturing during the operation of driving` or sinking the columns, I arrange in the wall the longitudinal iron or other beams or girders 7, against which the transverse beam 2 bears. Any desired number of beams or girders 7 maybe arranged in the wall, but in the drawings I have represented four beams of I shape in cross-section, although they may be of any desired form.

The hydraulic jacks may be utilized in the arrangementv shown for raising or lowering the wall to any required extent.

After two or more columns have been driven at opposite sides of the wall the transverse beam may be placed, as at, S, Fig. 2, upon the upper ends of the columns and built upon for thepurpose of'peri'ecting the ol'd Wall, and thus placing beneath it al permanent subbase. or foundation, as, will be readilyfunderstood, or a beam, as at 9,l may be placed on the: upper ends4 of the; columns and constitute a-,supfport i'oruprights l0, Figs.` 4 and 5, bearing against longitudinal beams or gird'ers 12, inserted inte the old wall oro-ther structure, so,

that the latter can be sustained during the" l I claim istime: thaty any alteration is made therein or whil'ethe: lower portion of the wall i-s being The uprightslO` reconstructed or repaired., may be. iron posts of any desired shape in cross-section and their upper ends may bear aga-inst plates 123, which abut the longitudinal beams; or girdersf l2.

In the` modification, Fig.v 6, a transverse beam 1i is. inserted at one end into or through the wall l, and at theother endmay be;A provided a heavy weight, as at 1'5. The. weight. 15, if used, is. preferably arranged on a support 16suspended from the beam 14 suspending-rod 17 or other device. The hydraulic jack 18- operates against they beam 14' in juxtaposition tothe building-wall 1, for

the purpose ot driving. the tubular columns 19: perpendieularly into the earth. The col u-rnns 19 are made the same the columns: heretofore described; that is, each is com.- posed of sections which arey successively driven orV sunk by the jack..

in 7 is represented the manner in which a transverse; beam 2O is-supported by tubular columns driven or sunk into the earth at one side of they wall l through the medium of thev hydraulic jacks, as hereinbefore explained. In t rs-.arrangement the beam 20 and tubular columns at one side of the wall of the old or already-erected building constitute; a base or foundation for the erection of a new build'- ing-wal'l or other structure.

In Fig.. is represented in plan view the longitudinal beamsV or gird'ers 7 against which theztrans-verse beams 8, Fig. 2 bear to sup;-A port an existingl wall.

The arrangement shown in Fig. 6 isv advantageous and useful for driving the colunrns at one side of any structure for form.-

a foundation close to such structure to erect ano-ther building or other object'.

1 part of the same collapsing.

ardere In the present invention the f ulcrum against which the hydraulic jacks work is the transverse beam, one or more, inserted into the wall and having their projecting end or ends acted upon by the jacks. The transverse beam, one or more, is resisted in upward motion by the superincumbent weight of the existing wall or other structure.

The transverse beam 2, one or more, may bear directly against the masonry of the wall or other structure, but it is advisable to have the beam, one or more, bear against the longitudinal beams or girders 7, inserted into the wall, as hereinbefore explained.

It will be evident that while the old wall or other structure is supported by the jacks it can be extended downward to any required depth without danger ot' the building or any It will also be observed that by placing the posts 10 on the beam i), one or more, the wall l can be supported at any desired height above the foundation, thereby permitting any alteration in or reconstruction of the lower portion of the Wall.

Having thus described my invention, what 1. The method herein described of con structing a foundation for a building-wall,

i or other structure, which consists in inserting a beam transversely into the wall, or other structure, arranging hydraulic jacks in engagement with said beam outside the vertical plane of thewall and successively driving column-sections perpendicularly into :the earth until a. column is formed which ireaches bed-rock, or other firm substrata,

substantially as described.

2.. The combinati-'on with a buildingwall,

" or other structure, of a beam inserted transversely into; the wall andi projectinglaterally there-from, and a hydraulic. jack engaged with l the laterally-projecting end of the beam and `arranged perpendcularly to successively drive the sections of tubular columns. into `the' earth until a column is form-red which reaches bed-rock, or other `firm substrata, substantially as described.

3. The combination vwith a building-wall, or other structure, of abeam inserted transversely intothe wall and having its ends projecting from opposite sides thereof, and hydran-lic jacks al-ranged' at opposite sides of the wall, or other structure, and engaged with, the projecting ends of. said beam to successively drive column-sections perpendicularly into the earth until.' columns are produced which reach bed-rock, or other strata, and are located at opposite sides of the wall or other structure,substantially as described. In testimony whereof I have hereunto set my hand in presence of two subscribing wit- HGSSGS.
